FASTENER FOR THE MEETING-RAILS OF SASHE'S.

SPECIFICATION forming part of Letters Patent No. 476,947, dated June 14,1892.

Application filed November 10, 1891- Serial No. 411,428. (No model.)

T0 all whom it may concern.-

Be it known that 1, CHARLES G. LINDSKOG, a citizen of the United States,residing at Salt Lake City, in the county of Salt Lake and Territory ofUtah, have invented certain Iinprovcments in Locks for the Meeting-Railsof Sashes, of which the following is a specification.

My invention relates to that class of devices which are employed to locktogether the meeting-rails of sashes and the like in order to preventthe raising or opening of the same from the outside.

The object of my invent-ion is to provide a lock of this general classwhich shall be of neat appearance, easily applied, simple and completein construction, and so arranged and constructed as to seriously hinderthe opening of the window even from the inside of the building except bysuch persons as are acquainted with its operation. In addition to thismy lock provides means whereby the crack or space ordinarily existingbetween the saslrrails is automatically and completely closed by theclosing of the window whether the lock is used or not.

My invention will be hereinafter fully described, and its novel featurescarefully defined in the claims. i

In order that my invention may be the better understood, I haveillustrated in the accompanying drawings the preferred form there of,which drawings I will now describe.

Figure 1 is a perspective view of the central portion of apair ofwindow-sashes, showing the lock in plan, the rails being cut incross-section, so as to show the arrangement of the Weatherstrip ordevice for closing the opening or space between the rails, whereby theentry of cold air, dust, &c., to the building is prevented. Figs. 2 and3 are views of the opposite faces of the lock proper, which is adaptedto be set in the top rail of the lower sash, these views being drawn toa scale somewhat larger than that of Fig. 1. Fig. 4 is a face view ofthe central portion of the weather-strip, showing the device for holdingthe same securely to the lock proper when the sashes are lockedtogether. Fig. 5 is a view on a smallerscale, showing the position ofthe parts when the sashes are unlocked or the lock in its inoperativeposition; and Fig. (3 is a similar view showing the position of theparts when the lock is applied to hold the sashes together, and alsoillustrating the form of the plates or devices for the ends of the railsfor bearing and automatically dropping the Weatherstrip into place asthe rails meet in closing the window. Fig. 7 is a sectional view on alarger scale, showing the position of the various parts when the sashesare locked together.

In the views, A represents the lock proper as a whole, and B representsthe weather strip, which in reality constitutes a part or auxiliary tosaid lock and serves not only as a guard to prevent the entry of coldair or dust, but to hold the two sashes firmly and securely together.

Referring toFigs. 2 and 3 especially, a is the escutcheon or plate ofthe lock, which is adapted to be countersunk in the top rail of thelower sash and is provided with a central opening a, through whichpassthe two hinged jaws l) c of the lock proper, the outer ends I) 0,respectively, of which are somewhat hooked, in order to provide a firmhold thereon by the fingers of the operator. These jaws are hingedtogether at d, the jaw c being provided with a recess and jaw b with acorresponding ear b through which car and the body of the jaw 0 passesthe pivot-pin d, as will be readily understood. On the end of jaw c isformed a hook 0 with a rounded up per surface, and the end of jaw 19 iscorrespondingly curved and hollowed out, so that when the jaws areclosed, as seen in Figs. 2 and 3,an open space will be left behind thehook as seen in said views. Said jaws b and cbeing hinged together at dand the said pivot-pin being on a line with or back of the plate a,pressure on the projecting ends of said jaws will tend to open them, asseen in dotted lines in Fig. 2. A spring 6, secured to the plate a andbearing on jaw 0, serves to keep said jaw normally in place, but by itselasticity allows of the opening of the jaws under pressure. In order toinsure the proper opening of the jaws, I prefer to recess the sides ofthe jaws slightly at c b, as seen in Figs. 2 and 3, s) as to allow of alittle play; but the opening a in plate a is made the full width of thejaws, so as to admit of their being readily drawn out in releasing thesashes. Referring to Fig. 7, f is a metal pin or bolt passing throughthe lower rail of the upper sash and secured in position in any manner,either by riveting or by means of nuts. This pin is in position when thelock A is pushed in to take between the jaws b 0 thereof, forcing themopen and compressing the spring e, and enters into the space between thejaws behind the hook 0 above referred to. Thus it will be seen that thetwo rails are firmly and securely locked together and will not yield toany pressure except the jaws be opened by pressure on the projectingends thereof.

I will now describe the construction and arraugement of the Weatherstripdevice, referring more particularly to the last four figures of thedrawings. The meeting-rails of the respective sashes are grooved ontheir inner or contacting faces, and on each side of the sash, over thegroove in the upper sash, is secured a plate 9, (seen in Fig. (5,) whichis preferably of stout-metal plate set or countersunk in the sash. Thestrip B is provided at its ends with pins or studs 71, set securelytherein, and these studs pass through and find hearings in the plates g,as will be readily understood, whereby said strip is held againstendwise movement, but allowed to swing freely upon said studs as pivots.On the sides of the lower sash and just over the groove therein ismounted a hooked plate 11,

which is also countersunk, so as not to inter fere with the raising orlowering of the sash in its grooves, and on the ends of the strip B,

at the free sides thereof, are set other pins or studs 7, which whensaid strip is in its vertical position, as illustrated in Fig. 5, are inposition to be engaged by the hooked end of plates 1 on either side ofthe top rail of the.

lower sash and thrown down into the position seen in Fig. 6, therebyentering the groovein said rail and completely closing the space betweenthe rails, as will be understood, said strip when in the position seenin Fig. 6 touching'the floors of the grooves along its whole length. Atthe middle of the strip B,

where the lock A is set, is secured by screws or the like a metal plate7c, which has at its center, as shown, a raised head or projectionbinding of the parts I have illustrated the. groove m provided at itsend with abevel m 1 and bead Z provided with a bevel Z. On the plate a,and projecting from the lower face of the opening a is provided a pinit, which also takes into said groove in jaw b, as seen in dotted linesin Figs. 3 and 7, and which serves as a limiting-stop to prevent thelock proper A from being wholly withdrawn.

My invention, while particularly designed as a lock. for themeeting-rails of sashes, may as well be employed as a lock for otherpurposes, and by colorable changes may be converted into a lock forcloset and sliding doors, &c.; and I do not of course wish to beunderstood as limiting myself to the precise construction andarrangement herein shown, as this may be varied to a considerable extentwithout materially departing from my invention.

Having thus described my invention, I claim 1. In a lock for themeeting-rails of sashes and the like, the combination, with the rails,one of which is provided with a pin or projection, of the hinged jaws cI), mounted in the other rail and adapted to take about said pin as theyare pushed in, whereby said rails are locked together, substantially asset forth.

2. In a lock for the meeting-rails of sashes and the like, thecombination, with the rails, one of which is provided with a pin orprojection, of the hinged jaws c 1), adapted to take about said pin, oneof said jaws having a groove m in its side, the escutcheon-plate throughwhich said j aws play, and the pin a on said plate, arranged to takeinto the groove in said jaw, substantially as and for the purposes setforth.

3. In a lock for the meeting-rails of sashes and the like, thecombination, with the rails, one of which is provided with a pin orprojection, of the hinged jaws mounted in the other rail and adapted totake about said pin when pushed into place, and the weather-strip B,mounted in grooves in the rails and adapted to be dropped to ahorizontal position when the rails come together, said jaws when intheir operative position holding said weatherstrip in its horizontalposition, substantially as and for the purposes set forth.

4. In a lock for the meeting-rails of sashes and the like, thecombination, with the rails, one of which is provided with a pin orprojection, of the hinged jaws mounted in the other rail and adapted totake about said pin, the weather-strip B, pivotally mounted to play ingrooves in the rails and provided with a stud j, and the hooked plate 2on one of the rails, arranged to take against said stud j on theweather-strip as the rails meet, whereby said strip is dropped to itshorizontal position, said hinged jaws when in their operative positionholding said weather-strip securely in place, as and for the purposesset forth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
